This would do two things. One, it would (possibly) prove that AI cannot fully replace human writers. Two (and not mutually exclusive to the previous point), it would give you an alternate-reality version of the first story, and that could be interesting.

this is just “imagine if chatbots were actually useful” fan-fiction

who the hell would want to actually read both the actual King story and the LLM slop version?

at best you’d have LLM fanboys ask their chatbot to summarize the differences between the two, and stroke their neckbeards and say “hmm, isn’t that interesting”

4 emdashes in that paragraph, btw. did you write those yourself?
